Databases of DOE Complex-Wide Contaminants of Interest

This page provides a compilation of on-line, interactive databases containing dose coefficients, screening benchmarks, and human health effects databases that may result from exposure to various contaminants found in the environment. These values are typically applied in performing dose and risk assessments.

Ecological Databases
•	Ecological Risk Analysis: Tools and Applications	ORNL	Site contains information that can be used to conduct ecological screening and baseline risk assessments.
•	EPA software for calculating Ecotox Thresholds for selected chemicals	EPA	EPA has developed software that calculates Ecotox Thresholds (ETs) for selected chemicals and can print out a table of ETs and their sources.
•	Screening Benchmarks Reports	ORNL	Five documents that discuss the determination of ecological benchmarks for aquatic biota, wildlife, terrestrial plants, sediments, and soil invertebrates.
Dose Assessment Databases
•	Dose Coefficients from Federal Guidance Report No. 11	ORNL	This is an interactive site which allows the user to retrieve inhalation and ingestion intakes for radionuclides.
•	Dose Coefficients from Federal Guidance Report No. 12	ORNL	This is an interactive site which allows the user to find dose coefficients for air submersion, water immersion, and contaminated ground surface for several depths for radionuclides.
•	EPA's Federal Guidance for Radiation Protection	EPA	This web page gives Federal and State agencies, researchers, students and the general public information on Federal guidance for protecting the public from the harmful effects of radiation.
•	EPA's Integrated Risk Information System (IRIS) Database	EPA	IRIS is a data base of human health effects that may result from exposure to various substances found in the environment, including DOE sites. Click on the Substance File List button to go to a list of the available substance files; then click on any file name on the list to open that file.
•	HEAST Table 4 Slope Factors	EPA	HEAST Table 4 slope factors, user's guide and radionuclide table
•	Exposure Factors Handbook	EPA	The EPA Exposure Factors Handbook provides a summary of the available statistical data on various factors used in assessing human exposure.
•	ITER Database	Private	Pilot database and interface containing risk information on 39 chemicals.
